Hi ladiesI got a BFP on Tues and am booked in for a scan on 21st April to check all ok.EC was 16th March and ET was 18th March.How do I work out my due date? Is it 38 wks from ET i.e. 40 wks from 2 wks before ET which in a natural pregnancy would have been my last LMP?? I won't get a due date until the scan and know its early but I just wanted a rough idea...

Congrats! You can use this site's due date calculator. The link is http://www.ivf-infertility.com/calc_preg.php You can find it under the Resources tab as well at the top of the page. I entered your information and got Monday December 6, 2010. You are 4 weeks 2 days pregnant today! YAY!!!
